Tell anyone and everyone your idea without fear they're going to steal it.
Solve a real problem and the world is yours.
It's okay to doubt yourself, it's okay to feel down; just never give up.

Solve a real problem. You don't start a company because you want to be an entrepreneur or the fame and glory that comes along with it. You become an entrepreneur to solve a real problem.
